Benefits of technology

The present invention provides a cross-linking agent compound that can create a strong and flexible polymer with improved absorption ability. Additionally, the cross-linking agent compound has a unique aroma that can help reduce odor and create a natural feel for use.

Problems solved by technology

When the cross-linking density of the base resin is low, the absorption ability is increased but strength is weak, so that the shape cannot be maintained in the subsequent steps.
When the cross-link density is too high, strength is increased but the water absorption ability may be deteriorated.
Further, the super absorbent polymer prepared by polymerizing an acrylic acid-based monomer has a characteristic odor of acrylic acid, and when it is used for hygiene products such as diapers, it is accompanied with an unpleasant odor when urine or the like is excreted.
However, there is a problem in that physical properties of the super absorbent polymer such as absorption ability and permeability are deteriorated, or caking phenomenon occurs in which the super absorbent polymer aggregates or hardens with time.

synthesis example 1

[0075]

synthesis example 1-1

[0076]408.7 g of geraniol was dissolved in 700 ml of ethanol and stirred. Acetic chloride (942 g, 856.4 ml, 4 equiv.) was slowly added dropwise while maintaining the reaction temperature at 30° C. When the conversion and termination of the reaction were confirmed by TLC, the solvent and the unreacted materials were removed by evaporation under reduced pressure. The obtained dichloronate compounds (a mixture of Pc and Tc) were used in the next reaction without any further purification.

[0077]Pc (CDCl3, 500 MHz): 5.50-5.45 (m, 1H), 4.13-4.07 (m, 2H), 2.16-2.06 (m, 2H), 1.83-1.53 (m, 13H)

[0078]Tc (CDCl3, 500 MHz): 6.00 (dd, J=16.87, 11.00, 1H) 5.27 (d, J=16.87, 1H), 5.12 (d, J=11.00, 1H), 2.16-2.06 (m, 2H), 1.83-1.53 (m, 13H).

synthesis example 1-2

[0079]The dichloronate compounds (a mixture of Pc and Tc, 522.9 g, reference material) obtained in Synthesis Example 1-1 were put into an acetone aqueous solution (1.5 L) of about 80% purity, ZnO (427.2 g, 2.1 equiv.) was added, and the mixture was refluxed at a temperature of 100° C. When the conversion and termination of the reaction were confirmed by TLC, the temperature was cooled to room temperature. Thereafter, the solid precipitate was removed using a filtration filter, and the remaining acetone was removed by evaporation under reduced pressure. The remaining organic material and a small amount of water were removed by fractional distillation to obtain desired diol compounds (a mixture of Pa and Ta).

[0080]Pa (CDCl3, 500 MHz): 5.43-5.41 (m, 1H), 4.17-4.12 (m, 2H), 2.12-1.97 (m, 2H), 1.75-1.13 (m, 13H)

[0081]Ta (CDCl3, 500 MHz): 5.91 (dd, J=17.10, 10.52, 1H) 5.22 (d, J=17.09, 1H), 5.07 (d, J=10.52, 1H), 2.06-1.97 (m, 2H), 1.76-1.13 (m, 13H).
